Abstract
EL SISTEMA DE COMUNICACIONES COMPRENDE: UNA PLURALIDAD DE ESTACIONES (BS1...BSN) DE BASE DISTRIBUIDAS, ESTANDO CADA UNA OPERATIVAMENTE ACOPLADA A UNA RED PUBLICA DE TELECOMUNICACIONES CONMUTADAS (PSTN), Y ESTANDO ADAPTADA A COOPERAR CON UNA O MAS DE UNA PLURALIDAD DE UNIDADES TELEFONICAS PORTATILES INALAMBRICAS (CT1...CT4) MEDIANTE UNA PLURALIDAD DE CANALES DE COMUNICACION DIGITALES INALAMBRICOS, QUE FUNCIONAN SOBRE UNA BASE DUPLEX POR DIVISION EN EL TIEMPO. LA UNIDAD DE BASE (BS1...BSN) SE DISPONE AL DETECTAR UNA LLAMADA ENTRANTE DE LA RED DE CONMUTACION PUBLICA, PARA SONDEAR TODAS LAS UNIDADES TELEFONICAS PORTATILES INALAMBRICAS (CT1...CT4) MEDIANTE LA TRANSMISION, SOBRE UNA BASE CICLICA, DE LA IDENTIDAD DE LAS UNIDADES PORTATILES A CONECTAR A LA LLAMADA ENTRANTE, SOBRE UN CANAL SELECCIONADO, Y LA UNIDAD DE BASE (BS1...BSN ESTA DISPUESTA A DISPERSAR CADA OPERACION DE SONDEO CON UN MENSAJE DE SEÑALIZACION. CADA UNIDAD PORTATIL (CT1...CTN) ESTA DISPUESTA A EXAMINAR LOS CANALES INALAMBRICOS,EN UN INTERVALO PREDETERMINADO, Y LA UNIDAD DE BASE (BS1...BSN) ESTA ADAPTADA A POSPONER EL ENVIO DE UN MENSAJE DE LLAMADAS A CUALQUIERA DE LAS UNIDADES PORTATILES (CT1...CT4) HASTA QUE HAYA TRANSCURRIDO UN PERIODO PREDETERMINADO DESDE EL COMIENZO DE LA ACCION DE SONDEO, SIENDO EL PERIODO PREDETERMINADO SUSTANCIALMENTE SIMILAR A, PERO MAYOR QUE, EL INTERVALO PREDETERMINADO.
